Beit Aknownthat we, CHARLES A. LIND- s"rir 'fi,\i, ol Allegheny, andJOHN F. Srnnrn, of Avalon, Allegheny county, Pennsylvania, have inventeda new and useful Steel Car,oi" which the vlollowir'ig is a ilull, clear,and exact description, reference being had to the acernnpanyingdrawings,'forming part oithis specification, in Which- 'lfigure 1 shows in planview the underi'raine oi a car embodying our invention. `Fig. 2 is aside elevation thereof. Fig. 3 is a vl-,irtical section on the line llllll of Fig. l. Fig. 4 is a eross-sr-retion on' the line IV IV oi Fig. 1.Fig. 5 is a detail View showing a inodiiication. Fig. o is a top planview showing a niodiiiel l'onstruetion. llig. 7 is a longitndiiizfilsection on the line Yll Vil of' Fig. 6, and Fig. 5% is a side elevationthereof.

(iur invention is designed to provide a steel ,ear-'fram e forstreet-railway ears having end platforms at a lower level than the maini'rarne of the car-body and to make the con-, struction ol greatstrength and durability.

"lhe preferable forni of our invention is shown in 'the drawings, inwhich 2 represents the bolster, 53 the end sill, and 4 1 the side sills,oi the ear-trarne, which are made ol suihibly-llaiigerl nietai beams orpieces.

'.lhe platiorin-i'ranie has inain platformsilis 5 :')gwhich extendforwardly of the'cnd sill 2% at a lower horizontal plane. At or near theend sill'tliese sills 5 5 are curved upwardly, e, to the level of theside sills and are iiixed thereto, extending along the side sills to :ipoint back of the bolster, thus reinforcing the s e sills and.strengthening the underirarne of the car at the bolster. VEach of theplatiorrii-sills 5 can be made in anpintegral pi'eee or, as shown in thedrawings, in sections riveted together. They are supported by metalbrackets 7, which depend from the 'end sills and terminate preferably inC-shaped supports, which embrace and are lixedto thesills 5. rlfheentire weight ofthe platforrn can thus he carried from Vthe end sill bythe sills 5.

The remainder of the platform-frame is composee` ot beams 8 8 and,9 9,which are iixed to the under side of the end sill 3 at their inner endsand extend thence to the platform Specification ef'Letters Patent.Application tiled August 12,19-03. Serial No. 169,246.

is bent downwardly or flanged at its forward edge and is fixed to amarginal angle 12 either on the inner or outer side thereof. Thisailords a still and very strong end construction to the plat'l'orn'i.Fig. 5 shows the angle 12 fitted to the inside of the plate 11.

ln the ligures on the third sheet of the drawings the end sill 3! is setat a lower level than the side sills and the platformdieams 9 Q extendbaell to the bolster as continuations of the center sills c e and aresupported iroin the end sill by brackets 7 Within the scope ot ourinvention as defined in the claims the construction may be modified invarious ways, since What We claim isq 1. A car-frame havingdiagonally-extending metal platform-sills suspended from the undertraineof the ear, the rear portions of said sills being bent u wardly andextending along theside sills oil) the underfra'me to a point back olthe bolster, thereby reinforcing the side sills and strengthening theunderframe ol the car'at the bolster; substantially as described. 2. A-car-frame having metal platf0rinsills suspended from the underframe ofthe ear and extending in a direction obliquely to the center line o fthecar, and a flanged platforni end sill overlyixw the forward ends of theplatforrn'- sill and having a .'rnarginal flanged anglesecured thereto;substantially as described.

3. A car-frarne having an end sill, side'sills and bolster, metalplatformsills below the level of the 'side sills extending upwardlyalong the same to the bolster and fixed to the side sills, saidplatform-sills being sup ortedon open-sided brackets attached to t e endsill substantially as described. y v

4. A car-frame having flanged metal latforrn-sills below the mainunderframe o the car and suspended therefrom, said Vplatformsillsextendlng upwardly and iiied to the earrame back of the end sill, andC-shaped brackets suspending the platform-sills"fromthe end sill;substantially as described.

5. A car-fraine having 'a platform, and a IOO .and amarginal'flanged`beamg sgbstantially' .set ourvhands..
